ROLLER-HARROW.

SPECIFICATION forming part of Letters Patent No. 730,837, dated June 9,1903.l

Application filed January 13.1902. Serial No. 89,406. (No model.)

To alla/hom it may'coneern:

' a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same.

The presentinvention is designed to produce a very simple but elfectiveform of roller adapted for the crushing, pulverizing, and leveling ofland.

The object of my invention is to provide a land-roller wherein a pair ofpulverizers are mounted upon independent shafts whose inner ends arejournaled in a `hinged frame capable of lateral movement.

A further object is the provision of hinged boxings at the outer ends ofthe shafts of said pulverizers to permit of the movement of their innerends.

A still further object is the provision of a series of rollers formingsaid pulverizers, joined by suitable spindles or rods land in the use ofspacing collars or rings interposed between the matching faces of therollers to hold them apart from each other.

These several objects are attained'in the following manner and by themeans hereinafter described and claimed, reference being had to theaccompanying drawings,in which- Figure 1 is a sectional plan of myimproved roller. Fig. 2 is a partial elevation and sectional view of oneof the rollers. Fig. 3 is an end elevation of one of the frame parts.

In the drawings I have shown a main framesupport comprising ahorizontally-arranged frame-support 1 and the transverse end-connectedframe parts 2, secured as shown. At the inner ends of the frames 2 Iprovide the rectangular openings 3 for a purpose to be furtherdescribed.

4 4f, 5 5, and 6 are pulverizing-rollers, those designated as 4 5 beingat the extreme outside and those designated as 4 5a being the innermatching rollers, and the rollers referred to as 6 being those arrangedbetween the rollers 4 4 5 5. These rollers are substantially ring shapeand combined in the manner show n form what are commonly known aspulverizing-rollers'.k They are each provided with serrated or rollingperipheries, as shown yat 7. To join the several rings' in a series toform a' roller, I provide for retaining them held apart from each other.This is accomplished by the use of spacingcollars 8 and spindles or rods9, the latter passed through openings in the rollers 4, 5, 4, and 5 andintermediate rings 6. Between adjoining faces of each ring and rings androllers is employed a separate'seres of the spacing-collars 3surrounding each rod used for retaining the parts together. Thisarrangement of spacing-collars leaves openings between the rings 6, withthe exception of the small spaces where the collars 8 are placed, andpermits all dirt and weeds to fall between themv and aids in keeping therings free of dirt and weeds. It has a further tendency of breakingclods of dirt which must fall between the open faces of the rings to theground. By serrating or notching the peripheries, as shown, it aidsmaterially in breaking up the ground on which the roller is worked.

The rollers 4 5 4au 5"L are each provided with web portions 10, and 1l11a are suitable bearings or boXin gs in which are journaled'shafts 12,upon which the rollers rotate and to which they are attached by the samepassing through the web portions 11 and 1l, as shown.

The bearings or boxings 11, in which the outer ends of the shafts 12 arecarried, have a swinging relation with the frames 2. The boxings arecarried in the openings 3 of the frame 2 in the manner shown in Figs. 1and 3 and have swelled portions, through which pass pins 13, securingthe same to the frames in a pivotal manner, the openings 3 being ofsufficient size to permit of movement of said boxings.

The boxings 11, in which the inner ends of the shafts 12 are journaled,are of peculiar construction and are connected with each other and toauxiliary means in a manner to permit of a swinging or lateral movementbeing imparted to the inner ends of the pulverizing-wheels. The boxingshave the ear portions 14, having a swinging connection at 15,

ICO

' having slotted portions at 17.

VIS

18 is a tongue or pole supported from the frame 1, and 19 is a segmentalrack which is secured to the tongue in a suitable manner. L

2O is a lever-carrying means for engaging with the segmental rack 19 andis pivoted at 2l, and the outer end of said lever has pivotal connectionwith a supporting bar or 1ever 22. This lever extends back, and at itsinner end by means of a bolt or pin 23 hasI connection with theextensions 16 through the slotted portions 17.

In operation the pnlverizer may be'retained in the position illustratedin the figures, rol1`t ing parallel with the frame parts in which theyare jo,urnaled, or have their inner ends` shifted laterally to travel inangles oppositelyf to each other. This is accomplished by throw-g ingthe lever 2O forwardly,'shifting the lever? 22 rearwardly, which willcause the boxings 11*L to swing upon their pivot 15, the boxings; 11 atthe outer ends of the shaft hinged in4 the frame in such a manner as topermit of: such lateral movement of the pulverizers at their inner ends.The extensions 16 havei bevel matching faces which will permitof. theirbeing brought close together.

The rollers 6 4 5 4a 5L may be assembled very quickly in the mannerillustrated and the pnlverizers shortened or lengthened, as may bedesired.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is-

1. A combined roller and harrow, comprising a shaft, oppositely-placedwheels rotating on said shaft, a series of rings carried between saidwheels, rods for supporting the rings, the rods having connection withthe Wheels, and aseries of spacing-collars surrounding said rods betweenthe rings, sub- Vfor holdingthe rings apart from each other carried bysaid rods, all substantially in the manner shown and forthe purposedescribed. 3. In a combined roller Vand harrow,the combination'with amain frame, two independent shafts havin-g their outer ends journaled inswngably-arranged boxings and -their inner ends journaled in sectionsofa boxing having a common pivotal center, wheels carriedk upon oppositeends of each shaft'to rotate thereon, a series ofrings interposedbetween eachn pair of wheelsand secured for rotation therewith by meansof'a series of rods as shown, a separate series of spacingcollarssurrounding each rod between adjacent faces of the rings, substantiallyas described.l p

In testimony whereof I aflxvmy signaturel in presence of two witnesses.
